 If we consider energy efficiency of animals in movement blue whales score higher than tuna though whales are heavier than tuna. The mammal consumes less energy per unit weight than the fish when they travel the same distance.
Neelesh Patankar, professor of mechanical engineering at Northwestern University, Australia, has come up with a new measure that allows comparison of animals as small as bees or zebrafish with animals as large as albatrosses or blue whales. Given their size and shape, each animal is able to spend the least amount of energy to move the most distance. The idea that animals are tuned for energy-efficient locomotion is not surprising, but the authors have devised a fresh approach to the issue of how to compare the efficiencies of different animals,”said John Dabiri, professor of aeronautics and bioengineering at CIT
Patankar finds, as he had hoped, that small animals find themselves in low *Reynolds number situations, and large animals find themselves in high Reynolds number situations. This means they expend energies differently, which is what Patankar’s coefficient represents. Using the coefficient, one can compare the energy efficiency of bodies weighing few grams to many tonnes. The coefficient also indicates that animals that fly are less energy-efficient than those that swim. This, Patankar thinks, must be because those in flight have to expend more energy to counteract gravity than those in water.
The unique contract-and-relax action of jellyfish allowed it to recapture some of the energy it spends on motion. This means a jellyfish can travel a lot more distance for the same amount of energy spent by other animals adjusted for its weight and size.
*Reynolds number explains the relationship between two forces that act on any body that is moving through a fluid. The first is viscous force, which is, simply put, the push you feel when you put your hand out of a moving vehicle. The second is inertial forces, which is the tendency of a moving object to keep moving (or that of a stationary object to remain stationary).

Man is a social animal and as such thrust of his progress can be measured in terms of the society, created by him.
If it is created measure of his success can also be determined in how sociable he has become. In the evolution of our ape-ancestors to the modern man we hold no distinction between Australopithecines, Homo erectus (which inhabited Asia, Africa, and Europe) and Neanderthals (either Homo neanderthalensis or Homo sapiens neanderthalensis) (which inhabited Europe and Asia). We carry however in our genome something of those groups that have died out. We are humans and our achievements are part of our common experience. In short despite of evolutionary twists and turns of our origins we bear the bequest of those who did not make it. Family beginnings of modern man go far back as 400,000 and 250,000 years ago. In terms of biology we humans do not demonstrate in the least any particular divine favor that a Christian, Jew or a Muslim claim as special for himself.
But looking at our social structure we see we are fragmented in the way we have chosen to show our identity in terms of our race, religion and economic status. We went about creating a family of man and became a creature of our own conceit. Perhaps this paradox is ever in our consciousness and that would explain the perennial popularity of Mary Shelley’s novel Frankenstein.
We choose the society that we can relate to and not other way around. In accommodating members with various life experiences and interacting with them we infuse vitality into it. We broaden our horizons as a result. Nature has divised ways which would seem to follow this formula: like repels like; and opposites attract. History is replete with instances where societal collapse owed to the failure in heeding Nature’s warning. Inbreeding of Pharaohs in Egypt sowed their eventual demise and one of the serious consequences of Islam lay in the cultural stagnation. Dar-ul Islam or Global Islam means that all nations would be ruled under an Islamic theocracy, which is simply a national government set up under the rule of Allah’s divine sanction as expressed in the Qur’an and Shari’ah law. It did not happen. Historically Muslims failed to make their initial successes in world conquests to something permanent or significant. Mongol Invasion of the 13th century and Black Death had curtailed their mission. In their falling back to their old ideas a way of life they were comfortable they denied further growth. Compare between the period of Ottoman Empire at the height of its glory during the reign of Suleiman the magnificent, and the decades prior to the WWI (when it was called the Sick Man of Europe) is a sad commentary of a society that had run of ideas. It ceased to grow.

Islam as a religion can be authoritatively dated and the flight of Mohammed is a historical date. Let us consider Islamic tradition relates Prophet Muhammad in 610, when he was 40 years old first heard the voice of the angel Gabriel, who recited to him the word of God, today written down in the Muslim holy book, the Qur’an, meaning “recitation.”
It is significant that Muslims believe that what Gabriel told Muhammad came directly from God;by the same token the Jews believe the promise of Israel was given by God to Patriarch Abraham indicating the extent of their promised land.
One cannot be true and the other false.
Islam says that the message was similar to those received by the early Hebrew prophets: that God is one, he is all-powerful, he is the creator of the universe, and that there will be a Judgment Day when those who have carried out God’s commands will enjoy paradise in heaven, and those who have not will be condemned to hell. As we have seen, these ideas were also part of the Zoroastrian religion. When certain ideas are common experience of man there must be something to it. But in the way these ideas are coined and given value we need to be clear that such value system is man-made and as currency holds limited use. The correspondence principle states that if one man’s revelation is accepted as true on the same scale every belief must be accepted as true.

Man who dreams the impossible is everywhere persecuted. It is not the dream but how that dream is realized for the betterment of society is the main point. Prophet Mohammed fled to Medina and his dream was put into reality by his followers. How one would make a case for the Mormon sect, which was also founded on a spiritual experience?
This sect was founded in 1830. The Mormon pioneers were members of The Church of Jesus Christ of Latter-day Saints, also known as Latter-day Saints, who migrated across the United States from the Midwest to the Salt Lake Valley in what is today the U.S. state of Utah. At the time of the planning of the exodus in 1846, the territory was owned by the Republic of Mexico, which soon after went to war with the United States over the annexation of Texas.

The journey was taken by about 70,000 people beginning with advanced parties sent out by church fathers in March 1846 after the assassination of Mormon founder Joseph Smith made it clear the faith could not remain in Nauvoo, Illinois — which the church had recently purchased, improved, renamed and developed because of the Missouri Mormon War setting off the Illinois Mormon War. The well-organized wagon train migration began in earnest in April 1847, and the period (including the flight from Missouri in 1838 to Nauvoo) known as the Mormon Exodus is, by convention among social scientists, assumed to have ended with the completion of the First Transcontinental Railroad in 1869. Whether preposterous or wholesome values that a religion may contain man is ready to forsake all for his liberty of conscience. It is the golden key which opens the door to the promised land.
How can Moslems expect others to accept their religion as perfect when they themselves did not keep the promise? History of mankind shall be strewn with the conflict of liberty of conscience and pursuit of pleasure whatever the term ‘pleasure’ may mean. History is not concerned with motives or dreams of man but how their dreams were realized. When the children of Islam fell back from the shared experience of the rest of the world they nullified even what was within their reach to be at the vanguard of progress.
Dreams of a prophet like Joseph Smith or Brigham Young will please many but for me to accept these under coercion would be veritable nightmare. (To be continued)

Truth is absorbed into the very fabric of Nature, that does not lose its significance even when it is shown up as matter. It is in the heart of atom, that you may call micro cosmos; micro cosmos corresponds with our cosmos or macro cosmos. (ref: Correspondence principle) Truth is not compromised even when matter is compounded into identifiable objects. Every element is in context of Truth by which Cosmos holds together. We may see a part  of it and it is our visible  universe.
2.
God is Truth that is the basis for all religions. In the case of Christianity core value is the belief that Jesus descended from God, and took the form of man; died  and ascended to the right hand of God.
God is also love. God as Truth remains constant whereas Love connects. When I speak of my beloved it means simply that I have someone to whom I am connected. Truth cannot change form but it can render love on the basis of Truth. If Jesus is in context of Truth so we are all,- as explained in the first section. Love incarnate (‘A body hast thou prepared for me’, so prophesied the Psalmist.) is Truth given a human face.

A principle is the ultimate basis for our actions.
The correspondence principle exists on account of the fact same matter is the basis for life forms and our universe. At the level of atoms we are all one. Using material nature as the key we create some semblance of order out of cosmic events. (What we observe in our visible universe provides grist to our intellectual mill.)
Oneness is the template from which we correspond micro cosmos with macro cosmos however infinite it may be. Thus any idea that we tease out of Idea we consider as valid. Being finite and unable to work effectively with Time-Space what scale shall we adopt? Only thing that we can commend for such a measure is that the correspondence principle works. Yes to our time and place.
Thus we hold certain values as constant. Energy is constant. Another is Truth.  Absolutism is what gives our principles its validity. When one says God is our father we draw the conclusion using correspondence principle. Reverence to one who has given life to us is in the fitness of things. Truth is perceived as inherent in such an earthly conduct towards our parents. In Correspondence principle the equation of idea to Idea can only be changed in the idea and not in what is Absolute. A parent as giver of life is an idea so is God as the father. Nevertheless how we let the principle shape our conduct can only change our view of Idea not other way about.

Correspondence on the matter of size: Our planet earth is a living planet giving rise to millions of species of life forms; Because it is a home to every creature big or small, these life forms have learnt to interact in groups forming a food chain, and thriving as far as they could, making the most of their ecosystems. Crack open an acorn and one might find a world of creatures that make it their home during the nut’s growth and decay. The number, however, is limited considering the size of the acorn. The nut has its limit so has the earth. Such a comparison is based on idea and we thus make sense of this world and beyond.
Ideas are very potent since these are our working tools to carve out niche for ourselves. Even so it has a limit when we correspond with Idea since we, finite creatures, cannot contain Idea on its infinite scale.
